The Context

alt text

You are reading War and Peace, from the writer Liev Tolstoy.

It is easy to be overwhelmed by dozens of characters with tongue-twisting names, and you are also confronted with distances described in “versts”

But what is a verst?

Why?

Liev Tolstoy 1897” by F. W. Taylor

Calculation: Not Exaclty Easy

One can learn to calculate distances “on the fly”:

So you read that Pyotr Ilyich walked 2 ¼ versts – what is this in miles?

  length.in.miles <- 2.25 * 0.6629
  return(length.in.miles)
  [1] 1.491525

Now for Kilometers – if Ippolit Vasilyevich rode 5 2/3 versts

  length.in.km <- 5 * 1.0668 + (2/3) * 1.0668
  return(length.in.km)
  [1] 6.0452

And so on…
